Colorful Swarm of Robots

I want to make a swarm of 20 glowing small robots and choreograph them, like Disney's pixelbots ( but for 1/10 the cost (each of their robots costs $500. They are wireless (bluetooth low energy) and controlled via an position feedback overhead camera or just open-loop.

I've made three working robots already and want to make more.

Disclaimer: I developed these for a hopeful-commercial project. It's only reasonable to make a few robots on our budget right now, but I really want to make a swarm of them, because that'd be cool and I always wanted to say that I've controlled a swarm of robots to do my bidding. Who wouldn't?
